[more ▼] This review focuses on an emerging class of controlled radical polymerization named Organometallic-Mediated Radical Polymerization (OMRP). The latter is based on the temporary deactivation of the growing radical species by a transition metal complex and the reversible formation of a carbon-metal covalent bond. Initially developed with cobalt complexes, OMRP has extended to several metals today. As highlighted here, the choice of the metal, the structure of ligands, temperature, and additives deeply affect the course of the polymerization and its mechanism. Macromolecular engineering opportunities offered by OMRP are also described, as well as practical applications sustained by the resulting polymer materials.

[more ▼] This communication will focuse on recent progress in the field of cobalt-mediated radical polymerization (CMRP). For example, the beneficial impact of cobalt complexes on the course of acrylate and vinyl chloride (VC) polymerizations will be discussed. The addition of conjugated unsaturated derivatives, like dienes, fullerenes and carbon nanotubes, onto (co)polymers preformed by CMRP has also been investigated. Similarities and differences between these radical addition processes will be presented as well as the potential applications of the resulting copolymers and carbon based materials for photodynamic therapy (PDT) and electromagnetic interferences (EMI) shielding.

[more ▼] Transition metal-assisted polymerization techniques have always played a crucial role in polymer synthesis. As an illustration, metallic compounds have deeply marked the field of living/controlled radical polymerization (L/CRP) which gives access to well-defined polymers under non drastic conditions. Indeed, atom transfer radical polymerization (ATRP) is one of the most successful methods to polymerize vinyl monomers in a controlled manner. Besides this very successful system, another metal-assisted CRP technique is emerging, i.e. organometallic-mediated radical polymerization (OMRP). In contrast to ATRP, OMRP involves the reversible formation of a covalent bond between a transition metal and the polymer chains, which strongly decreases the extent of termination reactions and leads to polymers with predictable molecular weights. This lecture aims to provide a comprehensive overview of the synthetic and mechanistic aspects of OMRP as well as major achievements and remaining challenges in this field.

[more ▼] Cobalt-Mediated Radical Polymerization (CMRP) is an efficient tool for polymerizing acrylates and vinyl esters. However, a challenge in CMRP remains in controlling the polymerization of both types of monomers with the same cobalt complex. Here, we show how Co(acac)2, efficient for unconjugated vinyl monomers, can also cope with acrylates.

[more ▼] Mesoporous carbon fibers were prepared by controlled pyrolysis of poly(vinyl acetate)-b-poly(acrylonitrile) (PVAc-b-PAN) copolymer located inside a cylindrical nanoporous template. A melt-compression method was developed to help the penetration of the infusible copolymer inside the template without the use of any solvent that ensures the formation of completely filled fibers instead of nanotubes. The influence of the composition of the PVAc-b-PAN copolymer and the heating rate during pyrolysis on the porous morphology of the fibers was studied by transmission electron microscopy (TEM).

[more ▼] The micelles of a recently synthesized copolymer of poly(vinyl alcohol)-b-polyacrylonitrile added to the growth solution of the filamentous yeast Trichosporon cutaneum strain R57 led to the formation of a binary system consisting of micelles and cells. The resulting micelle/cell system was studied as a model for the removal of toxic concentrations of heavy-metal ions (cadmium and copper) from aqueous solutions. The ion-removal efficiency mediated by this system was higher than for free-floating cells. The copper-removal efficiency from the solution reached a level of 65% after 24 h of cultivation, whereas the cadmium-removal efficiency reached 62% after 6 h of growth. For comparison, the free-floating cells removed 42% of copper and only 38% of cadmium from the solutions. The effects of surface interactions between the cells and polymer micelles on the biosorption capacity of the cells are discussed in the article.
